Cast iron e fana ka nako e telele empa e ka eketsa boima ba 'mele. Tšepe e sa hloekang e fana ka ho leka-lekana pakeng tsa matla le boima ba 'mele, ho ntlafatsa katleho ka kakaretso. Lisebelisoa ka bobeli li tlameha ho mamella khatello ea mocheso le mochini ho boloka ts'ebetso e nepahetseng le ho fokotsa mesi.

Taolo ea Mocheso

Taolo ea mocheso e bapala karolo ea bohlokoa taolong ea mesi. Mohaho o mongata o tlameha ho qhala mocheso ka nepo ho thibela mocheso o tukang o feteletseng. Lithempereichara tse phahameng li lebisa ho eketseha ha sebopeho sa NOx. Taolo e nepahetseng ea mocheso e thusa ho boloka mocheso o tlase oa ho tuka, ka hona ho fokotsa tlhahiso ea NOx. Lisebelisoa tse tsoetseng pele le lirafshoa li ka ntlafatsa bokhoni ba mefuta e mengata ea ho laola mocheso.

Tlhahlobo ea Phallo ea Matla

Lintlha tse Amang Phallo ea Matla

Exhaust Flow Dynamics

Matla a phallo ea motlakase a bapala karolo ea bohlokoa ts'ebetsong ea enjene. Moralo oa manifold exhaust ka ho toba o susumetsa tsela eo likhase tse tsoang ka ntle ho enjene li tsoa ka eona. Mefuta e mengata e entsoeng hantle e tiisa ho phalla ha khase e boreleli le ka potlako, ho fokotsa moferefere. Sena se fella ka phefumoloho e ntlafalitsoeng ea enjine le matla a ntlafatsoang. Hangata lienjineri li ntlafatsa sebopeho le bolelele ba liphaephe tse ngata-ngata ho fumana litšobotsi tse ntle tsa phallo.

Kgatello ya mokokotlo

Backpressure e bolela khanyetso eo likhase tse senyang li kopanang le tsona ha li tsoa enjene. Khatello e phahameng ea mokokotlo e ka sitisa ts'ebetso ea enjine ka ho thibela phallo ea mosi. Lihlooho tsa ho qeta tšebetso li ikemiselitse hofokotsa ho hanyetsa ho phalla, ka tsela eo e eketsa bokhoni ba enjene ea bophahamo ba modumo. Motlakase o ka tlaase o lumella enjene ho leleka likhase tsa ho qeta ka mokhoa o atlehileng haholoanyane, e leng se lebisang ho phaello ea matla a matla. Thee sa tsoa etsoa exhaust e ngatameralo hangata e shebana le ho fokotsa khatello ea maikutlo ho matlafatsa ts'ebetso ea enjene.

Ho Boloka Mocheso

Ho boloka mocheso ka har'a mefuta e mengata ea ho tima ho ama ts'ebetso ea enjene le tlhahiso ea matla. Mocheso o feteletseng o ka lebisa ho mocheso o phahameng oa ho tuka, o ka fokotsang ts'ebetso ea enjene. Taolo e nepahetseng ea mocheso e thusa ho boloka mocheso o nepahetseng oa ts'ebetso. Lisebelisoa tse tsoetseng pele le lirafshoa mohahong o mongata li ka ntlafatsa ho qhala ha mocheso. Ho boloka mocheso o nepahetseng ho tiisa hore enjene e sebetsa ka har'a mocheso o nepahetseng oa mocheso, ho eketsa tlhahiso ea matla.

Teko ea Ts'ebetso

Tlhahlobo ea Dyno

Teko ea Dyno e fana ka tikoloho e laoloang ho lekanya ts'ebetso ea mefuta e mengata ea ho tima. Baenjiniere ba sebelisa dynamometer ho etsisa maemo a sebele a ho khanna. Mokhoa ona oa tlhahlobo o lekola tšusumetso ea mefuta e mengata ho phallo ea matla, torque le ts'ebetso ea mafura. Teko ea Dyno e fana ka lintlha tse nepahetseng, tse nolofalletsang baenjiniere ho etsa liqeto tse nang le tsebo mabapi le moralo o mongata le khetho ea thepa.

Teko ea 'Nete ea Lefatše

Teko ea 'nete ea lefats'e e tlatselletsa tlhahlobo ea dyno ka ho lekola mefuta e mengata ea ho ntša metsi tlas'a maemo a sebele a ho khanna. Baenjineri ba lekola hore na mefuta e mengata e sebetsa joang maemong a fapaneng, joalo ka ho khanna teropong, ho tsamaea ka maoto litseleng tse kholo le ho potlakisa lebelo le matla. Teko ea 'nete ea lefats'e e thusa ho tseba mathata afe kapa afe a ka bang teng a sa hlahelle tikolohong e laoloang. Mokhoa ona o pharaletseng o tiisa hore mefuta e mengata ea exhaust e fana ka ts'ebetso e ts'oanang maemong a fapaneng a ho khanna.

Tlhahlobo ea Papiso

Tlhahlobo ea papiso e kenyelletsa ho lekola meralo e mengata e fapaneng ea ho ntša motlakase ho fumana hore na e ama phello ea eona ho phallo ea matla. Baenjineri ba bapisa lintho tse kang matla a phallo ea mosi, khatello e ka morao, le ho boloka mocheso. Tlhahlobo ena e thusa ho tseba meralo e sebetsang ka ho fetesisa ea ho ntlafatsa ts'ebetso ea enjine. Ka ho bapisa mefuta e mengata e fapaneng, baenjiniere ba ka supa matla le bofokoli ba moralo o mong le o mong. Ts'ebetso ena e lebisa ntlafatsong e tsoelang pele le boqapi ba theknoloji e mengata e fapaneng.
